, Application filed April 30, 1915. Serial No. 24,868.

To all whom it may concern: 4

Be it known that I, EMILE WAL MEIER, a citizen of the United States, anda resident of Gulfport, in the county of Harrison and- State ofMississippi, have invented an Improvement in Air-Regulators for Engine-Manifolds, of which the following is a specification. The presentinvention relates to gasolene engines and more particularly to anauxiliary valve attachmentassociated with the carbureter thereof andadapted to automatically regulate the quality of the mixture beingsupplied to the cylinders. x The primary object of the invention is theprovision of a device attached to theimanifold of the engine andautomatically operated by the inrush of air from the radiator and enginefan to increase or decrease the amount of air intake to the mixture inconformity with the speed of the engine,

A further object is to provide an attach-- ment of this character whichmay be appliedto' engines of ordinary construction and which is durable,efficient in carrying out the purpose for which it is designed andinexpensive to manufacture.

-' appended claimsfor this The inventive ideainvolved is capable ofreceiving a variety bf mechanical expres sions, some of which for thepurpose of illustrating the invention, are shown in the accompanyingdrawing; .but it isto be ex-;

pressly understood that the. particular con.- struction shown in-the-drawing is used merelyitofacilitate the description of theinvention as a whole, and not to define the limits thereof,- referencebeing had to the purpose. a 'In the "drawing Y Figure 1 isadiagrammatic'view of a gasolene engine showing the-invention applied'thereto,

Fig. 2 is an enlarged 'viewof the" device showing-the same in itsmaximum-open position.

Referring more particularly to the accompanying drawing in which 1' ereference Fig. 3 is a section taken substantially on the line.33 of Fig.4.

. reduced externally threaded end 16 of a connection 17 theouter end ofwhich is enlarged as indicated at 18 and also provided with externalthreads. internally threaded cylinder 19 having an' open inner end isthreaded upon the enlarged portion 18 of the connection 17 and adjustedthereon inv any desired position.

The top of the cylinder 19 -is enlarged as shown at 20 and has securedto this enlarged portion, by means of set screws 21, an angular bracket22 having a depending portion 23 which extends in frontof the'outer endof the cylinder 19 and spaced a distance therefrom. The closed outer endof the cylindex 19 is provided with a centrally located opening in whichis mounted a small bearing pin 24 extending longitudinally of thecylinder 19' and having its ends pointed as shown. The depending portion23 of the alinement with. thebear'ing pin 24, adapted to receive; anadjusting'screw 25,'the inner Specification of Letters Patent. P t ted M13, 1917 bracket 22 is provided with an opening, in

end of-which formsa bearing for the adjacent pointed end of said pin..The cylinder 1.9 also'hasmounted therein a disk 26 which isadjustable-longitudinally of said cylinder and prbvided centrallythereof with an opening, in al'inement with thebearing pin 24, adaptedto receive ascrew 27,-similar to screw '25, the inner end. of'whichengages the adjacent pointed end of the pin 24.

The portion of the pin 24 projecting be yond the outer end-of thecylinder 19 has pivotally mounted .thereon an oscillating 'plate 28'havingan 'arcuate slot 29'therein "which is adapted to register with asimilar slot-30 inthe closedend .of the cylinder 19 when-the parts are'in the position shown in Fig. 2. The air is .then' permitted to .passthrough said slots and openings 31 formed 13 where itmixes 1th theoriginal mixture in the disk 26 and-thence into the manifold' 'l'l'ofrom the carbureter14. If desired a plurality of spacing rings 32 may beinserted into the cylinder 19 between the outer end thereof and the disk26. The oscillating plate 28fis adapted to abut the outer end of thecylinder 19 and is provided with a relatively large vane 33 the plane ofwhich extends at right angles to the plane of said plate. A spring 34 iscoiled about the inner. end of the bearing pin 24 and has one of its.

ends secured in the cylinder 19 while the other end thereof is connectedto a pin 35* whichprojects through the arcuate slot 30 in the cylinder19 and has its outer end secured in the;plate 28. This spring 34 isadapted :to normally retain the vane in the position shown in Fig. 5when the slots 29 and 30 are out of registry. It will thus be apparentthat the vane 33 is moved toward the position shown in Fig. 2 againstthe tension of the spring 34. r

In practice, when the engine is running at a normal or slow speed theinrush of air from the radiator and engine fan 11 is insufficient toovercome the tension of the spring 34 and move the vane 33 to theopening position. However, when the speed 'of the car and, engine isaccelerated sufliciently to cause the pressure of air against the vane33 to move the same toward the left, as shown in the drawing, the plate28 will be oscillated about its pivot 24 untilthe arcuate slot 29therein registers with the slot-30 in the cylinder. 19 when air willpass therethrough into the manifold, as previously described. If thepressure of air against the vane is sufiiciently strong the same will betion through the medium of the spring 34.
